What is the maximum permissible bandwidth for a single sideband emission on the 2 meter band?

In amateur radio, particularly on the 2 meter band, the maximum permissible bandwidth for single sideband (SSB) emissions is essential to understand for effective communication and compliance with regulations. Single sideband emissions are typically very narrow, allowing for efficient use of the available spectrum. The correct bandwidth limit for SSB on the 2 meter band is 3 kHz.

This limit helps to minimize interference with adjacent channels and allows more users to operate within the band. Each emission type has a specific bandwidth rule set forth by regulatory bodies, like the FCC in the United States. The 3 kHz limit ensures that SSB operations remain clear and efficient, contributing to better overall performance in this segment of amateur radio.

In this context, other bandwidth options exceed what is considered permissible for SSB, making them less applicable. Understanding these limits aids operators in adjusting their equipment and practices to comply with regulations while maintaining effective communication.
